A Dessert for St. Patrick: Irish Brownie Bombs

You’ve had your Guinness in a cold mug, your whiskey straight up and your Bailey’s in a mixed drink, and of course maybe all in one for an Irish Car Bomb. But this St. Patrick’s day let’s try it in a dessert with some Irish Brownie Bombs.

It’s a classic brownie bottom with some Guinness mixed in the batter. On top of the brownie is a cheesecake layer blended with some Bailey’s. Finally, mix your Jameson whiskey shot into the three leaf clover piping. And there you have it, Irish Brownie Bombs that won’t leave you with a black-eye.

Order up!

    Does the brownie layer taste very guinness-y? I’ve tried a bunch of guinness recipes but the chocolate flavor is always too powerful

  • Chris March 17, 2012  

    My brownies are in the oven in the last cheese cake phase….My cute little clovers have smudged and are just brown spots….Any suggestions if I try these again? I tried to do the small clovers as pictured in this article rather than 3 big clovers as stated in the recipe. Will let you know how they taste later. Taking them to a party tonight. Cheers and happy St. Patricks Day!

    Brownie recipe calls for 1 tablespoon vanilla, but in directions step one it states “add 2 teaspoons vanilla”. REALLY. keep things straight. whomever adapted this recipe should have proof read before posting.

    Hey Paul – I agree! Sorry that was me. I’ve fixed the recipe. Thanks for letting me know!

    Hi Chris-Try piping a circle and then use a toothpick to drag a line towards the center of the piped brownie batter all the way around to create the three leaf clover.
